Product details
Overview
R5F111NGALA#U0 from Renesas is an RL78/L1C 85-pin VFLGA microcontroller without USB, featuring 96 KB Flash, 10 KB RAM, integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (13-channel), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD-based metering and control panels.
For engineers reviewing the R5F111NGALA#U0 datasheet, R5F111NGALA#U0 pinout, R5F111NGALA#U0 application, or R5F111NGALA#U0 equivalent, key selection considerations include its 85-pin VFLGA (7 × 7 mm) package, absence of USB PHY, industrial-grade temperature range (−40°C to +105°C), and dedicated LCD voltage boosting circuitry with CAPH/CAPL terminals.
Technical Context
The R5F111NGALA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.04167 μs (@24 MHz) to 30.5 μs (@32.768 kHz), and includes multiply/divide/accumulate instructions. It integrates a 12-bit interval timer, real-time clock 2 (RTC2) with calendar and alarm, and watchdog timer using the dedicated low-speed on-chip oscillator.
Its peripheral set includes four UART/LIN channels, five I²C/simplified I²C channels, four CSI (SPI-compatible) channels, eleven 16-bit timers, two 8-bit D/A converters, and two comparators with selectable internal/external reference. The LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111NHGLA#U0 | 128 KB Flash, 12 KB RAM, same 85-pin VFLGA package and peripheral set; no USB. | Supports larger firmware (e.g., multi-language UI, enhanced crypto libraries) without layout change. | Select when future firmware growth or added features require >96 KB code space. |
| R5F111MGAFB#30 | 96 KB Flash, 10 KB RAM, but 80-pin LFQFP (12 × 12 mm) package; no USB. | Requires PCB redesign due to different footprint, pin count, and pitch (0.5 mm vs. 0.65 mm). | Choose only if existing design uses LFQFP and thermal/mechanical constraints permit larger package. |

R5F111NGALA#U0 supports up to 44 segment outputs and 4 common outputs, enabling static or 1/2–1/4 multiplexed LCDs with up to 176 segments. This is verified in Section 1.1 Features and Figure 1-1 of the R01DS0192EJ0240 datasheet, which specifies "Segment signal output: 44 (40)" for 85-pin non-USB variants.
Which analog-to-digital converter resolution is available on R5F111NGALA#U0?
R5F111NGALA#U0 supports 12-bit A/D conversion when VDD is 2.4 V to 3.6 V, and 8/10-bit resolution at 1.6 V to 3.6 V. The 12-bit mode is usable across its full industrial temperature range (−40°C to +105°C), with 13 analog input channels including dedicated AVREFP/AVREFM references.
What package type and dimensions does R5F111NGALA#U0 use?
R5F111NGALA#U0 uses an 85-pin plastic VFLGA package measuring 7 mm × 7 mm with 0.65 mm pitch, per ordering information in Section 1.2 and package code "LA" in the part number. The "#U0" suffix denotes tray packaging, and the Renesas package code is PVLG0085JA-A.
Can R5F111NGALA#U0 operate from a 1.8 V supply?
Yes, R5F111NGALA#U0 operates across 1.6 V to 3.6 V, so 1.8 V is fully supported.
